Liposomal Quercetin adopts advanced liposome encapsulation technology, greatly improving the absorption and bioavailability compared with ordinary quercetin. It protects active ingredients from stomach acid degradation and delivers nutrients efficiently to the body.
Conventional quercetin is poorly water-soluble and easily degraded by stomach acid. Liposomal quercetin can be absorbed directly by cells, with stronger antioxidant and anti-inflammatory properties.
Available in custom grades from 50% to 90%, suitable for capsules, oral liquids, tablets and other dosage forms.
Active ingredients are not easy to degrade, with high temperature resistance and easy storage. Compliant with ISO, EP, USP and other international standards.

Liposomal Quercetin uses advanced liposome encapsulation technology. This shields the active ingredients from degradation in stomach acid and dramatically increases overall cellular absorption and bioavailability.
We supply customizable grades from 50% up to 90% purity. This ensures wide compatibility for different dosage formulations including tablets, oral liquids, and capsules.
It is primarily applied in healthcare products (for immunity support and blood pressure control), pharmaceuticals (to relieve cough and asthma), cosmetics (for anti-inflammatory and antioxidant properties), and as a feed additive for livestock productivity.
For 1kg shipments, we pack using double plastic bags inside an aluminum foil bag and an outer box. For orders of 10kg, 25kg, or more, we package using drums or cartons with double-layer plastic inner linings.
We support shipping by EMS, DHL, UPS, and FedEx for smaller weights (1kg-25kgs) taking 3-7 days door-to-door. Larger quantities are shipped by air (3-7 days to airport) or by sea (10-35 days to port) depending on your needs.
Yes, our product complies fully with international standards including ISO, EP, and USP, with strict control limits over heavy metals, purity (≥98%), and microbial activity.
